Sounds like it will be a blast. The nerves may just be from going solo then. Sounds like you know what your about though, so I'd just override any trepidation and go for it.

I did something similar a few weeks ago (admittedly with some friends). We were probably 40 miles from anywhere where we could flag down a car, and hiked into the woods several miles along the trail. My backpack broke inside the first mile, one of my friends slipped and fell into a stream, there were coyotes in the camp at night, and of course it rained. We all made it out sleepy sore and soggy the next, day but definitely felt better for having gone. Would do again.

You'll have a good time, no worries.
